I read a post on 7-30-15 .from Stebrock stating that if I sent my Blue ridge Windshield to Calsi I might get a new windshield which I did after contacting Calsi. Yesterday I got my new Calsci windshield, it took about one half hour to put on, I then took it for a 25mile ride and no more bobble head at any speed, I took it to 90mph and it performed flawlessly, this is a prototype and it still works perfectly.
